Cloudbreak is a very large arena. The take off zone runs up and down the long reef and the larger sets will break further out. It’s 7 miles from the nearest large island, fully exposed to swell, wind and currents. Conditions can change very quickly from hella fun to hella heavy.
Took my son there on a two week trip when he was 16 as well, back when we could stay on Viti Levu and take boats from Momi Bay each day to Cloudbreak. My son, about 5’6 at the time, spent much more time on his 6’6 step-up then his 5’10 daily driver.
Suggest you take the most board you would still be comfortable paddling, surfing, and hanging onto for dear life when caught inside. Why you’re pondering your step-up. why not borrow a racy looking board from a bigger friend, cruise a few. Give you an idea about paddle power and longer rail lengths, maybe help you decide on what board would work for you in well overhead to however big you want to surf. don’t need excessive rocker out there, keep some volume in the chest, foil out everything else. Get it glassed good, a little weight is a good thing with all the water moving, sometimes have to deal with wind, weight helps. 6/6,6 pretty typical for reef step-ups.
Keep this in mind. If from the boat Cloudbreak looks bigger, heavier then you think you’re ready for, you’ll be right. Which means you should be back at Restaraunts, where your daily driver will work fine.
Get good waves at Cloudbreak, it’s pretty magical. My son got a good barrel on his very first wave at Cloudbreak, an overhead drainer that took him well over a hundred yards down the reef in a hurry. He was never the same after…still isn’t…lol
If you happen to get scratched on the reef, pass on the ointments and such. Just cut up some limes, grit your teeth, and scrub the reef scratches thoroughly. Best disinfectant and healing accelerator for reef rash in the world, found out about it in Tahiti, works anywhere. Have passed that on to many who have benefited (lemons don’t work, different enyzmes.)
have a safe trip, mate…make some magic of your own…
